JAMES S. SPANGLER, OF CLINTON, MISSOURI.

ENSILAGE-CUTTER.

v Specification of Letters Patent.

Patented Dec. 22, 1914. A

Application filed July 20, 1914.. Serial No. 852,038.-

To all whom it may concern Beit known that I, JAMES S. SPANGLER, a

"I citizenof the United States, residing at Clinton, in the county of Henry and State of Missouri, have invented a new and useful Ensilage-Cutter, of which the following is a specification.

This invention relates to machines especially designed for cutting ensilage and it constitutes a division of an application filed in the United States Patent Office on Janu- R ary 20, 1914, Serial No. 813,254.

One of the objectsv of the invention is to provide a novel arrangement of adjustable fixed and movable cutting elements whereby the ensilage supplied thereto is quickly reduced to a finely comminuted state.

Another object is to provide simple means IIwhereby material is fed to the cutting memers.

With the foregoing andother objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of part'sand in the details of construction hereinafter described and claimed, it being" understood that changes. in the precise embodiment of the invention herein disclosed, can, be n1ade within the scope of what is claimed,w1 ,thout departing from the spirit of the invention.

In the accompanying drawings the pre-i ferred form of the invention has been shown.

' In said drawings Figure lis an elevar tionof an ensilage cutter and elevator embodying the present improvements. ,Fig. 2 is a plan view,'p arts being broken away.

i Fig. 31s a section on line A'B Fig. 2, parts i i' being ;-front elevation of the structure shown in Fig. 5. ,Fig. 7 is an enlarged section through top broken away. Fig. 4 is a section on line E-F Fig. 5. Fig. 5 is a side elevation of the mechanism employed for transmitting motion to the movable feed roll. Fig. 6 is a shaft 8-1. A supportingplate 85 is pivotally.

mounted at its lower end upon a transverse shaft 86cxtending adjacent one wall of the compartment 81 and journaled in the upper portion of this plate is the shaft 87 of a movable. feed roll 88. A sprocket 89 is secured to the shaft 87 and is engaged by an endless chain 90 receiving motion from a sprocket 91 secured to the shaft 86. A bracket 92 is fixedly connected to the wall of the compartment 81 and slidably engag ing this bracket is a rod 98 extending from the plate 85 and having a spring 94: thereon which bears against the bracket and again'st the plate and serves to press the roll 88' yieldingly against the roll 88, while at the same time permitting said roll 88 to move away from the roll 83.

A structure preferably in the form of a concave 95 is extended under the feed roll 83 and has a depending car 96 to which are pivotally connected jaws 97 having an arm 98 extending therefrom and outside'of the compartment 81. A cutting blade 99 is clamped between the jaws 97 and the bottom of the concave 95 and the jaws are held tightly against this blade by a set screw 100 which extends through the arm 98 and bears against the wall of the compartment 81, as shown particularly in Fig. 7. An adjusting screw 101 extends through the ear 96 and bears against the blade 99 so that, by means of this screw, the said blade can be, shifted beyond. the concave 95 to any extent desired. As shown in the drawings, more than one of these screws L01 c n be used. It will be noted that the concave fits close to the adjacent feed roll and has one end so disposed, as to constitute a combined guard ing and guiding portion whereby the mate.

rial when moving away from the feeding rolls is guided by the end of the concave to the cutting blade 99. If, however, any portion of the material should'adhere to the feed roll 83 which cooperates with the cloncave, the said guarding and guiding por-' tion of the concave would tend to strip said adhering material from the feed roll. It will be noted furthermore that the concave extends continuously along the periphery of the feed ,roll I through approximately onehalf the circumference thereof. This is ad vantageous for the reason that should material in. any manner pass the combinedguiding and guarding portion of the concave, it would be prevented from being thrown outwardly by the rotating roll 83 1 and would, instead, be guided so as to pass over the roll and down into position between the two feed rolls so that the proper feeding thereof to, the knife is insured. H

Cooperating With the blade 99 is a revoluble cutter including a shaft 102 having arms 103 each of which is provided With a head lOh'there being. an outstanding rib 105 along the backedge of each head. An arcuate cutting blade 106' is 'bolted'or otherwise secured upon each head and these blades are eocentrically arranged with relation to the shaft 10 2, their advancing or cutting edges traveling close to the free edge ofthe blade 99. Adjusting screws 107 may be mounted in the ribs 105 and may be used for shifting the blades 106 uponthe heads 104.- A motor 108 may be supported by a platform 109 on the frame 1, this motor transmittingmotion, through a sprocket 110, and a chain 111,,to a sprocket'112 securedto the shaft 102 of the revoluble cutter.- Another sprocket113 is drivenby the motor and transmits motion through a chain 114 to-a'sprocket' 115 secured to the shaft 86. A gear 116 rotates With shaft 86 and meshes with afgear 117 'secured'to a short shaft 118 on which is secured a sprocket 119. Mo tion is transmitted "from this sprocket through al'chain 120 to a sprocket 121 secured to the shaft 8 1 of the "roll 83.

- A sprocket 121 is secured to shaft 86jadjacent each of the compartments 81 and transv. When 'thefmotor is operated, motion Will be transmitted therefromthrough the variouschains, sprockets and gears to the rolls 83 and' 88 so. that, When the stalks are deposited in vertical or substantially vertical positions'upon these rolls, they 'Will be fed downwardly to f the coiiperatingfixed and movable cutters and thus quickly reduced to a comminu'ted state, the particles being directed downwardly into the compartment I 81. As the blades become Worn they'can be readily adjusted" by themeans described, as willbe obvious. 1 3 q For thelopurpose of removing the ensilage produced, an endless conveyer124 is mounted Withinthe trough 82 and extends through an upwardl and laterally inclined casing 125 to a discharge spout 126 This elevator is in the form of an endless belt made up of chains connected by cross cleats 127. The said chains engage sprockets 128 secured to a shaft 129 journaled Within thesides of the trough at one end thereof." A gear 130 rotates \v'ithjshaft'129 and meshes With a gear131lsecuredfto 'a shaft'13,2.'- v This shaft has s'p'rdoketl "which receives motion,

through chain 134, from a sprocket 135 secured to the shaft 86. Sprockets 136 are supported in the upper end portion of the,

casing 125 and are engaged by the chains ofth'e conveyer. Any suitable means, such asidler sprockets 137, can be provided for engaging-the chains of the conveyer Where the upper flights thereof pass into the casmg 125 from'trough 82. Furthermore the casing 125 can be hingedly connected to the trough, as shown at 138 so that, when the conveyeris not being used, "the casing 125 can bef'folded' upwardly out of'the Way.

It Will be understood of course that when the ensila'ge is deposited upon the conveyer it will be carried longitudinally in' the concave and having one endportion cooper ating With one ,o'fth'e faces of the concave to clamp the blade against movement, means carried-by the other end portion of said clampingmember and cooperating With fan 1 other ;face of the concave for holding the clamping memberin gripping pos tion, and

means for adjusting said blade between the clamping member and the concave and relative to the path of movement of the rotating outten' a i 4 g2. In an ensilage cutting machine, the

means, of a concave member" extending partly around said feeding means to direct.

under sized material around'and over said feeding means, said concave memberhaving' one end constituting a guarding and guiding portion to prevent over sized material from 4 entering between the feeding means and the.

concavemember and to guide material beloiv the said member, said concave member combination Livith' a cylindrical feeding havinga cutter seat on the outer undersun face of said concave member contiguous to the guarding and guiding end "thereof,

clamping means mounted upon the exterior convex portion'of said concave member and projecting over said seat, and meansvoper ating onsaid exteriorportion' for moving said clamping memberto clamp a cutter in said cutter seat.

In testimony that I claim the foregoing as'my own, have'hereto affixed my signature in the presence of two Witnesses.
